Issue Description

Build a parse query that uses $relatedTo and count, in order to get results and total count.
Parse uses the "Limit" parameter value in order to limit the $relatedTo query, this causes a incorrect count value to be returned.

Steps to reproduce

await Parse.Query.fromJSON('ExampleClass',
{
    "limit":15,
    "skip:"0",
    "where": {
        "$relatedTo": {
            "object": {
                "__type": "Pointer",
                "className": "RelatedClass",
                "objectId": "someObjectId"
            },
            "key": "examples"
        },
    }
})

Actual Outcome

result = depends on order desc or asc, if valid document is in range (0-15) it will show, but if not it will not.
count = returns lower count than actual count of valid documents (14 when there are 33 for example)

Expected Outcome

result = should return all documents that match upto limit so paging can work properly.
count = should return total count of all matching documents, regardless of limit.

Environment

latest, 5.4.3

Server

• Parse Server version: 5.4.3
• Operating system: ubuntu
• Local or remote host (AWS, Azure, Google Cloud, Heroku, Digital Ocean, etc): local

Database

• System (MongoDB or Postgres): monogdb
• Database version: 5.0
• Local or remote host (MongoDB Atlas, mLab, AWS, Azure, Google Cloud, etc): digitalocean

Client

• SDK (iOS, Android, JavaScript, PHP, Unity, etc): web
• SDK version: rest

Start at the Parse.Query.fromJSON entry point and trace how $relatedTo handles limit, skip, results, and count against MongoDB. Reproduce the case with 33 matching documents and a limit of 15; done means paging returns the limited matching results while count reports all matching documents.
